Very cool, thanks for sharing. Do you have access to 98 or 99 % ethanol alcohol? If so then when you have deaths you could preserve them in the ethanol (provided the body was still fresh) and submit them for DNA. Perhaps I could hook you up with a local university or museum to supply you with some alcohol. Where are you located?

Thanks again for sharing. I look forward to seeing your results and furthering our knowledge of these guys success in captivity. It would be great if we could breed these as easily as crickets, being they have a reported annual turn over.

How long have you had these females in captivity?

Hello Zach

On Thursday, I will be leaving for Long Beach to go to Long Beach state(Marine bio or bio major...so connections would be awesome).

If you are willing to cover shipping and keep everyone updated on them...I'd be willing to send them to you.(alive) I think the female who's laid eggs is gonna keel over soon but the younger female still has a good amt of time ahead.

An annual turnover? That is kind of odd. How would you explain all different age groups present at one time of year? That suggests to me they either live longer than a year or produce 2-3 generations/broods a year.

Overlap of generations occurs a lot in other arachnid groups such as Harvestmen. You can have adults, instars and eggs all existing at several points of the year.

However, the lifespan of each individual is still usually <1year.

Eg. You could get advanced offspring maturing whilst others are still in the juvenile stage (lets say in July for example) - and these adults could produce eggs, thus giving a situation where eggs, juveniles and adults all occur (eg July-August). In some cases, eggs that were layed late in the year may undergo some form of diapause and technically survive longer than 1 year (by overwintering as eggs or juves), although most will complete the cycle in under a year. This would allow for your observations of lots of different age groups, although without tagging and following specific individuals, it would be hard to say that they do/do not live for more than one season.

I think this could be the case for most solifgues. I think this is what Zach meant (apologies if I've gotten this wrong!)

These are for scientific research, DNA sequencing to be specific and ofcourse morphology. Contact Warren Savary to make sure they can reimburse you right now. You can send them priority mail, which should be around 6.00-12.00. Send them to:

Lorenzo Prendini
Division of Invertebrate Zoology
American Museum of Natural History
Central Park West at 79th Street
New York, NY 10024-5192
U.S.A.
Tel.: 212-769-5843


email Warren at WSavary@yahoo.com, tell him I referred you. Also let Dr. Prendini know when and what you are sending. This project can be largely influenced by material collected by field hobbyists, I encourage and thank all who can send material.

Once again check out this page for specifics on the project.

Hello Zach,

Didn't see the email in time since I am basically on the road right now.

I ask the two who received material from this project to cooperate with Zach when specimens are deceased(the spent female can probably be forwarded now, she chewed up a roach or two but doesn't actually feed anymore)...for the good of science and our hobby. Also, please keep the rest of us updated with photos and life history studies...whatever happens good or bad.

The older female arrived dead, gray and extremely smelly, the immature/small female seems healthy. Unfortunately there were only 2 eggs (there may have been as many as a dozen sent but the rest must have popped in shipping as they were sent in gravel/sand.) The eggs were placed in an incubator.

What a shame, if the animal is smelly then the DNA is probably too far degraded.

Shame on the adult female...but to be honest her days were numbered. I gave her a little roach prior to shipping which was refused.(chewed and spat out)

Is the specimen of any value to send to the address you posted for morphology?

Contact Warren Savary at the e-mail address that Zach provided. He'll be able to answer that question for you. (WSavary@yahoo.com) Meanwhile, I'll suggest to him that he check out this discussion.

The two eggs eventually shriveled up and died.
The small female seems healthy still.

Ah bummer. Last I heard from Wade some of his hatched.

GL with the remaining female!

Some did, and some are still alive. I cannot say I'm optimistic considering the hobby's collective trac record with these things, BUT still I'm happy it's not over yet!

I've got some pictures I'll try to post soon.

Well Wade, you can't say too many people have tried either!

I'm guessing you have them vialed up with some substrate to dig in?

Any luck with the Fresno Co. eggs?

Also, Eremobates sp. are said to feed mainly on termites. I think little subterraneans might be taken.

We find Eremobates hunting at night on our front porch and around lighted doors and windows during the early summer (before the monsoons arrive). Have not actually documented what they were feeding on, but it's obviously not subterranean. Once the rains arrive the Eremobates disappear - so perhaps during parts of the year when they are not hunting in the open they prey on subterranean prey.

On the flip side - we've seen Eremobates being preyed upon by scorpions (Centruroides), black widow spiders and Pholcid spiders.
